Convert a Text File from utf-8 to Windows-1252

Convert a text file from one character encoding to another. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    boolean success = false;

    // It's really simple:  Just load from one charset, save using another.

    CkStringBuilder sb = new CkStringBuilder();

    // In this case, my test file has some norwegian chars in the utf-8 encoding
    success = sb.LoadFile("qa_data/txt/norwegian_chars.txt","utf-8");

    // We could just as well write over the file we just read in.
    // (But I don't want to do that for my example..)
    success = sb.WriteFile("qa_output/norwegian_chars.txt","windows-1252",false);

    // Note:  Windows-1252 is a 1-byte per char encoding, which means it's only capable of representing
    // those chars in Western European languages.   See https://en.wikipedia.org/wiki/Windows-1252
    // 
    // utf-8 is an encoding that can handle chars in any language, including Chinese, Korean, Japanese, Arabic, Hebrew, Greek, etc.
    // If a text file contains chars in these other languages, obviously it cannot be converted to windows-1252 because
    // there are only 256 chars that can possibly be represented in a 1-byte per char encoding.

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
